Abstract
Epitaxial(1 1 1)NiFe/NiFeMn films were grown on (1 1 0) Mo/Al2O3 (1 1 - 2 0 ) structural templates by using MBE. Since the lattices mismatch between Ni Fe and Mo. the exchange field of NiFe/NiFeMn was induced by the stress in N iFe. The stress-induced exchange anisotropy resulted in dual shifted hyster esis loops. Because the lattice constant of NiFeMn is close to that of FeMn , the exchange field (135 Oe) of NiFe/NiFeMn is comparable to that of NiFe/ FeMn. (C) 2000 Elsevier Science B.V. All rights reserved.
